COMMENT ON Replace 25A Shunt Module for Magnet MXW5R03
COMPLETED MCC IFIX MSSQL DB Upgrade
I have successfully completed the MS SQL DB Upgrade at the MCC IFIX computer. The MCC IFIX system has been updated, tested, and validated to operate properly. All features, connections, data, and scripting have been transferred to the new DB, and tested to be fully operational. Upon completion, the entire IFIX system, in its current upgraded state, was backed up and its resulting restore files were saved into the ssg "O:" drive location.
The IFIX system is back online and has been returned back to OPS for operation.

Since this cavity has had vacuum issues starting 01/23/2018 at 6.7Mv/m and it has been on and off at everything above 7Mv/m up until this week at a ODVH of 7.0 Mv/m, I am going to set the ODVH to 5.0Mv/m until vacuum gets looked at by SRF or the trip levels get looked at. Last month it would trip with no more than a 2.24 W of CRFP with cavity 4 running at 8Mv/m. Cavity 3 vacuum needs to be checked out by SRF or we won't be able to run it above maybe 5Mv/m !
